Cat#:PA-2295F;Product Name:Rat Anti-Mouse Kappa FITC Antibody;Synonym:Ig kappa chain C region; HCAK 1; HCAK1; IGKC; Immunoglobulin kappa constant; Immunoglobulin kappa constant region; Immunoglobulin kappa light chain; Kappa 1 immunoglobulin light chain; kappa light chain; Km; MGC111575; MGC62011; MGC72072; MGC88770; MGC88771; MGC88809; kappa; kappa κ; kappa light chains, kappa κlight chains;Background:The immunoglobulin light chain is the small polypeptide subunit of an antibody (immunoglobulin). A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains. Antibodies are produced by B lymphocytes, each expressing only one class of light chain. Once set, light chain class remains fixed for the life of the B lymphocyte. In a healthy individual, the total kappa to lambda ratio is roughly 2:1 in serum (measuring intact whole antibodies) or 1:1.5 if measuring free light chains, with a highly divergent ratio indicative of neoplasm. The exact normal ratio of kappa to lambda ranges from 0.26 to 1.65. Both the kappa and the lambda chains can increase proportionately, maintaining a normal ratio. This is usually indicative of something other than a blood cell dyscrasia, such as kidney disease.;Description:Rat Anti-Mouse Kappa FITC Monoclonal Antibody;Host Species:Rat;Species Reactivity:Mouse;Application:FCM, IFM, ELISA;Storage:Store antibody products at 2-8°C.
